CONTAINER AND CAP THEREFOR Filed July 9, 1927 Patented Oct. 21, 1930 UNITED STATES PATENT OFFICE JOHN F. BLYTH, OF EAST ORANGE, NEW-JERSEY, ASSIGNOR T0 ELLIS-FOSTER COM- PANY, OF MONTOLAIR, NEW JERSEY, A CORPORATION OF NEW JERSEY CONTAINER AND car THEREFOR Application filed July 9, 1927. Serial No. 204,486.

This invention relates to containers and especially to those adapted for containing liquid foods such as milk and is concerned especially with glass containers such as milk bottles covered and protected by a paper covering in box-like form held in place over the bottle mouth by friction, by crimping, or by other means.

It has been proposed to press or draw pa employed for the purpose is fairly thick in order to secure suflicient strength for handling and this thick and rather stifi" paper does not lend itself readily to crimping. Even when impregnatedwith ahard wax such as carnauba wax, .heated and crimped over the bottle mouth 'a firm closure is not easily secured and furthermore, when exposed to moisture, to which, of course, milk bottles must be frequently subjected over-long periods, moisture is absorbed slowly into the paper, swelling'it sufficiently to cause the bended portions to expand and the cap to unfold to a degree such that it frequently may be readily pulled off the top with only very slight pull, much less than required in pick-.

.ing up the 'bottle by gripping the mouth with the hand in the usual way.

It is the purpose of this invention to provide acover, cap or stopper for milk bottles and a complete container comprising bottle and protecting cover free from the ob ections of unfolding in the presence of moisture which characterizes the ramekin type of hood %y reference to the accompanying drawings my invention will be made'clear. In the drawings like reference characters denote like .parts. Figures 1, 2, 3. and 4 show that part of the container which specifically concerns tle, which may be of the re the present invention, it being understood that these figures represent milk bottles, but to conserve space the lower gpart of the botnot shown. Figures 1, 2, 3 and 4 therefore show a portion of a bottle in elevation, with 'ulation type, is

the mouth portion in vertical section, the sections being taken along a diameter of the bottle mout In the drawings, A is a bottle having the closing device B, and the lid or cover CD. Thelatter preferably is made. in two parts, namely; of the disc D and the bended part or side 0. Instead of having the side C fluted, as in the case of the ramekin hood cap, the walls O are straight and smooth, like the sides of a pill box. To attach the disc D firmly to the top of the bottle, the side wall C is inturned at the top, as shown at E, forming a.

rim extending around the edges of the disc D. This form appears in Figures 1, 2, 3 and 4. The cover thus obtained may be simply forced onto the top of the bottle and held there by friction, or the lower portion of the sides C may be turned under at F to attach the cover more firmly to the bottle. As shown in Fig. 2 the flange of the bottle is rectangular in cross section, instead of being rounded as in Fig. 1, and the cover :is folded under the flange to make simply a right angle turn.

In Fig. '3 the bottle flange has a channel or groove H extending around it and the sides C are pressed into this channel to form the fold I. In Fig. 4 the same arrangement exists, but the bottle flange is tapering. It should be noted that the channel H may be omitted from the type of container shown in Fig. 4, and the cover made to fit the taper of the flange. Preferably the cover is slightly smaller so that merely forcing it onto the bottle mouth yields a firm closure.

Without the taper, but with a cover slightly smaller than the bottle mouth shown in Fig. 1, firm pressure on the cover forces it over the rounded flange and it thereupon gripsthe bottle in a secure manner without the aid of folding necessary when the cover is placed on the bottle.

The various operations of folding required to obtain the locking elfects shown in the drawingsmay be carried out-by means of appropriate apparatus after the cover has been applied to the bottle.

While I have shown the closure disc B separate from the cover C-D, it should be understood that in some cases I may employ a cover having a depressed part fitting into the recess just above 13 and serving as a stopper for the bottle.

Various waxes, resins, oils, and the like, may be used for waterproofing the paper material used inthe foregoing. In some cases the paper stock may be sized. with various waterproofing emulsions, such as a wax dispersion, so that it becomes adequately waterproof for the purpose. In other cases, especially when a waxed paper disc B is used as a separate closing means, the cover need not be madeparticularly water resistant.

The circular portion D may carry on its upper side any suitable emblem or advertising device.

Thus my invention relates to containers for milk, cream and similar beverages and foodstuffs comprising the combination of a bottle having a flanged mouth and a paper cover comprising a header-disc (D) and a side member (E) locked thereto, as for example, by folding or swaging one edge over the other to form a lock or seam or inter-locking fold, as the case may be; said side member fitting into close contact with the bottle mouth flange and preferably having substantially straight sides, that is, free from vertical foldings and plai-tings, but if desired having inturned or convoluted lower edges or other gripping means such as are illustrated, including the surfacing of the interior of the side walls with a slightly sticky or tacky substance, preferably employing a minimum amount of such coating almost invisible to the naked eye, to obtain additional adhesion or grip. Said container may have an auxiliary stopper or disc closure (B), or the header-disc (D) may have a depressed portion fitting into a recess in the bottle mouth and if desired be held in place by a disc forced into the depressed portion in order to clamp the recessed portion of the header-disc against the inner walls of said recess.

What I claim is 1. In containers for milk; cream and similar beverages and foodstuffs, the combination of a bottle having flanged mouth and carrying a protective paper cover comprising a header-disc and a side member folded into lockin engagement therewith, said side member fitting into close contact with the bottle mouth flange.

2, In containers for milk, cream and similar beverages and foodstuffs, the combination of a bottle having a flanged mouth and said side member fitting into close contactwith the bottle mouth flange, whereby the cover is securely attached to the bottle and does not substantially unfold within a reasonable time in the presence of moisture.

1. In containers for milk, cream and similar beverages and foodstuffs, the combination of a bottle having a flanged mouth and carrying a protective paper cover comprising a header-disc and a side member provided with an inturned edge folded into locking engagment therewith, the inturned edge exerting a firm grip against the bottle flange to secure the cover thereon and to prevent substantial unfolding in the presence of moisture.
